Covington’s tax group advises our multinational clients on their most significant and challenging tax issues. Most members of our group have extensive government experience, including several who have held senior positions at the U.S. Department of Treasury, the Internal Revenue Service, and the U.S. Senate. This experience, combined with our focus and creativity, enable us to develop bespoke solutions for sustained tax minimization in an increasingly regulated world. And, when our clients find themselves in a dispute with the tax authorities, we secure favorable results by efficiently resolving matters as early in the administrative process as possible, and before they are made public. Of course, when unable to achieve a desired outcome in this manner, we litigate.

Our team has experience across all tax disciplines, regularly working on bespoke issues with some of the largest multinational corporations, global financial institutions, sovereign wealth funds, sports teams and leagues, and foreign governments. We work closely with our clients on matters including structural tax planning for global businesses; transactional tax planning for mergers, acquisitions, dispositions, and restructurings; government representation before the IRS, Treasury, and Congress; resolving domestic and international tax controversies in the Exam, Appeals, litigation, and treaty processes; and the development, documentation, and defense of transfer pricing policies.
